Delivering Green Persuasion Strategies with a Conversational Agent: a Pilot Study

Climate change is undeniable. The drastic consequences it may have on our lives make a collective effort crucial. Our research explores how Conversational Agents (CAs) can persuade people into environmentally sustainable behaviors, particularly in domestic spaces where these technologies are becoming increasingly popular. In this research work, we conducted an empirical evaluation (N=29) exploring the effectiveness and stance towards the adoption of different persuasive strategies compared to a CA delivering messages referring to just one persuasion strategy. Furthermore, this contribution reports on a custom dialogue manager's implementation, designed to enable the execution of the experiment. Although study results suggested no significant difference in persuasion effectiveness and usability of the conversational agents, participants reported a significant difference in the perceptions of parasocial interactions and dialogue with the CA, preferring the one delivering multiple persuasive strategies.
